Possibly due to change brought about by the ACA, more small- and mid-sized companies are self-funding their healthcare plans, according to Kaiser Health News.

About 30 percent of companies with 100 to 499 employees are now paying for their workers’ health insurance claims directly instead of buying a health insurance plan. About 14 percent of small companies, with between one and 99 employees, are doing the same. These figures are up 19 and 7 percent, respectively, between 2013 and 2015. But larger companies, which historically have been the self-funding majority, have seen the practice decline.
